Thoughts on BOOX Tab Ultra C?

Does anyone here have a BOOX e-paper tablet? I'm a big fan of e-paper devices—I love my Pebble smartwatch, Kindle Paperwhite, and Light Phone II. I've been eyeing the Tab Ultra C for quite a while, and I am considering the pros and cons. Mostly, I intend to use it for browsing the web and maybe some light note taking and document writing.
